TIMER events could get keymodifier set - in this case the user assigned
spacebar modifier for setting views (running smoothview timer)
Also: cleaned op old hacks from event checking code.
The rule should be:
1) generate event properly, frozen state
2) pass on to handlers without exceptions or changing internal state
The only exception currently is for the "CLICK" (map key-release to unhandled
key-press).
Also: made --debug-event print OK. Slight cleanup in eventprinting in general.
It was putting the wmEvent state print in wrong place, doing it 4 or 8 times.
Any identifier that looks like an OpenGL identifier, but isn't, causes a false alarm by the glreport.py tool. Most of these were in comments so I just rephrased the comments. There were a couple of static functions/macros that were easy enough to rename. Only the glTexco and glIndex fields of the DMVertexAttribs struct was public and had non-local uses.
--debug
--debug-ffmpeg
--debug-python
--debug-events
--debug-wm
This makes debug output easier to read - event debug prints would flood output too much before.
For convenience:
--debug-all turns all debug flags on (works as --debug did before).
also removed some redundant whitespace in debug prints and prefix some prints with __func__ to give some context.
- made interface, windowmanager, readfile build without unused warnings.
- re-arranged CMake's source/blender build order so less changed libs are build later, eg: IK, avi
The problem was that wmPushMatrix/wmOrtho/.. and similar functions did not
work well for offscreen rendering. It would have been possible to make a
fake subwindow for this, but I decided to just remove this extra layer as
it does not seem to have much purpose and has been quite confusing when
trying to fix other bugs. The relevant matrices are already stored in
RegionView3D so there will be no increase in calls to glGetFloat, which may
have been a performance reason to use this system in the past.
set the draw method to triple buffer or overlap depending on the
configuration. Ideally I could get all cases working well with triple
buffer but it's hard in practice. At the moment there are two cases
that use overlap instead:
* opensource ATI drives on linux
* windows software renderer
Also added a utility function to check GPU device/os/driver.
* Convert all code to use new functions.
* Branch maintainers may want to skip this commit, and run this
conversion script instead, if they use a lot of math functions
in new code:

Preview renders:
- Added proper button type (BUT_EXTRA) for preview buttons, to
handle drawing better. It now first draws an alpha mask, to
ensure the preview is correctly fitting inside the widget style.
It then draws the outline.
- Added protection for executing preview renders while regular
rendering, that's not going to work...
Fixes:
- HSV picker didn't work. Old option "No Hilite" for buttons made it not
being checked for input anymore. Needs to be on attention list!
- Node editor wasn't drawing buttons correctly. Two things to keep track
off:
- Use wmLoadIdentity(), not glLoadIdentity()
- I've added a wmPushMatrix() and wmPopMatrix() version for correct
wm-compatible push/pop. Only one level for now.
WIP commit for new system to draw widgets and use themes or styles.
Not really interesting stuff to see in code now, the current
structure will change quite a lot, this to make it hook up well
to the existing system.
What works quite well is a new full opengl vector method to draw
scalable and pixel-aligned anti-aliased buttons.

* Triple Buffer is now more complete:
- Proper handling of window resize, duplicate, etc.
- It now uses 3x3 textures (or less) if the power of two sizes
do not match well. That still has a worst case wast of 23.4%,
but better than 300%.
- It can also use the ARB/NV/EXT_texture_rectangle extension
now, which may be supported on hardware that does not support
ARB_texture_non_power_of_two.
- Gesture, menu and brushe redraws now require no redraws at all
from the area regions. So even on a high poly scene just moving
the paint cursor or opening a menu should be fast.
* Testing can be done by setting the "Window Draw Method" in the
User Preferences in the outliner. "Overlap" is still default,
since "Triple Buffer" has not been tested on computers other than
mine, would like to avoid crashing Blender on startup in case
there is a common bug, but it's ready for testing now.
- For reference "Full" draws the full window each time.
- "Triple Buffer" should work for both swap copy and swap exchange
systems, the latter still need the -E command line option for
"Overlap".
- Resizing and going fullscreen still gives flicker here but no
more than "Full" drawing.
* Partial Redraw was added. ED_region_tag_redraw_partial takes a
rect in window coordinates to define a subarea of the region.
On region draw it will then set glScissor to a smaller area, and
ar->drawrct will always be set to either the partial or full
window rect. The latter can then be used for clipping in the 3D
view or clipping interface drawing. Neither is implemented yet.
Think global, act local!
The old favorite G.scene gone! Man... that took almost 2 days.
Also removed G.curscreen and G.edbo.
Not everything could get solved; here's some notes.
- modifiers now store current scene in ModifierData. This is not
meant for permanent, but it can probably stick there until we
cleaned the anim system and depsgraph to cope better with
timing issues.
- Game engine G.scene should become an argument for staring it.
Didn't solve this yet.
- Texture nodes should get scene cfra, but the current implementation
is too tightly wrapped to do it easily.
Editmesh code cleaned and compiling/linking. A whopping
20k lines back! :)
Not that it does stuff... editmode in/out has to be done,
and loads of operators. Also linking/exporting editmesh
calls has to be reviewed.
Also: added a blender_test_break() mechanism in BKE.
All of the view3d drawing code is now 'Context' free.
The idea is:
- ED_region_do_draw() sets and freezes drawing context
- regiontype draw() callback then can pass on other relevant
context stuff as function args.
Also cleaned up the WM opengl wrappers, to mimic opengl state;
no reason to give window pointer anymore.
Drawing code for space_view3d module.
It's still not cleaned, have to check on context usage still.
Also missing is editmodes, armatures, and probably more.
Known issue: splitting to 2nd window gives bad opengl lighting.
Picture for fun:

Current stat: brought back almost 10k lines! :)
Context API
This adds the context API as described here. The main practical change
now is that C is not longer directly accessible but has to be accessed
through accessor functions. This basically adds the implementation of
the API and adaption of existing code with some minor changes. The next
task of course is to actually use this design to cleanup of bad level
calls and global access, in blenkernel, blenloader.

Error, Warning and Debug Info Reporting
This adds the error reporting API as described here. It should help
clean up error() calls in non-ui code, but eventually can become used
for gathering messages for a console window, and throwing exceptions
in python scripts when an error happens executing something.

* Added functions to generate Timer events. There was some unfinished code to
create one timer per window, this replaces that with a way to let operators
or other handlers add/remove their own timers as needed. This is currently
delivered as an event with the timer handle, perhaps this should be a notifier
instead? Also includes some fixes in ghost for timer events that were not
delivered in time, due to passing negative timeout.
* Added a Message event, which is a generic event that can be added by any
operator. This is used in the UI code to communicate the results of opened
blocks. Again, this may be better as a notifier.
* These two events should not be blocked as they are intended for a specific
operator or handler, so there were exceptions added for this, which is one
of the reasons they might work better as notifiers, but currently these
things can't listen to notifier yet.
* Added an option to events to indicate if the customdata should be freed or
not.
* Added a free() callback for area regions, and added a free function for
area regions in blenkernel since it was already there for screens and areas.
* Added ED_screen/area/region_exit functions to clean up things like operators
and handlers when they are closed.
* Added screen level regions, these will draw over areas boundaries, with the
last created region on top. These are useful for tooltips, menus, etc, and
are not saved to file. It's using the same ARegion struct as areas to avoid
code duplication, but perhaps that should be renamed then. Note that redraws
currently go correct, because only full window redraws are used, for partial
redraws without any frontbuffer drawing, the window manager needs to get
support for compositing subwindows.
* Minor changes in the subwindow code to retrieve the matrix, and moved
setlinestyle to glutil.c.
* Reversed argument order in WM_event_add/remove_keymap_handler to be consistent
with modal_handler.
* Operators can now block events but not necessarily cancel/finish.
* Modal operators are now stored in a list in the window/area/region they were
created in. This means for example that when a transform operator is invoked
from a region but registers a handler at the window level (since mouse motion
across areas should work), it will still get removed when the region is closed
while the operator is running.
==========
* Changed wmOperatorType, removing init/exit callbacks and adding cancel
callback, removed default storage in favor of properties. Defined return
values for exec/invoke/modal/cancel.
* Don't allocate operator on the stack, and removed operator copy for
handlers. Now it frees based on return values from callbacks, and just
keeps a wmOperator on the heap. Also it now registers after the operator
is fully finished, to get the correct final properties.
* Changed OP_get_* functions to return 1 if the property is found and 0
otherwise, gives more readable code in my opinion. Added OP_verify_*
functions to quickly check if the property is available and set if it's
not, that's common for exec/invoke.
* Removed WM_operatortypelist_append in favor of WM_operatortype_append
which takes a function pointer instead of a list, avoids macro's and
duplicating code.
* Fix a crash where the handler would still be used while it was freed by
the operator.
* Spacetypes now have operatortypes() and keymap() callbacks to abstract
them a bit more.
* Renamed C->curarea to C->area for consistency. Removed View3D/View2D/
SpaceIpo from bContext, seems bad to keep these.
* Set context variables like window/screen/area/region to NULL again when
leaving that context, instead of leaving the pointers there.
* Added if(G.f & G_DEBUG) for many of the prints, makes output a bit
cleaner and easier to debug.
* Fixed priority of the editors/interface module in scons, would otherwise
give link errors.
* Added start of generic view2d api.
* Added space_time with some basic drawing and a single operator to change
the frame.
- removed editors/area and put this all in screen
- added first python calls (note, a new c file for scriptlinks)
- added view3d editor callbacks (no drawing yet)
- added files in editors/interface
(Cmake and Scons has to be fixed, help welcome!)
- now areas/headers are being converted on file read
- note: previously saved 2.50 files will crash!!! (.B.blend)
- area regions are being drawn, first handler for cursor added (on edge)
- window duplicate and scale works correct for screen subdiv
Todos for me:
- need to fix things in syntax (function names) a bit still
- more operators for screen
- define how Context will work... still unresolved when it gets set
- docs!
Reviews of code structure is welcome!
There are also more todos now for others, but it can wait a couple of days
